Four metrics are utilized to quantify the fusion results, including peak signal-to-noise ratio (PSNR) [1]} after tonemapping using \(\mu \) -law (PSNR-\(\mu \) ) and in the linear domain (PSNR-\(l\) ). We also use a quality metric developed specifically for the multi-exposure fusion of dynamic scenes MEF-SSIMd [2]}. In addition, to evaluate the subjective quality of HDR images, we use neural image assessment (NIMA)[3]}.
